This little dainty is seldom seen, although it is a wide-ranging orchid. This is due, probably, to the fact that it bears tiny flowers (only 3-4mm tall) on a narrow spike and grows in semi-dry grassy areas where it blends in quite well with the grass flower stalks. It also tends to bloom later than most of the spring orchids (such as
Spiranthes vernalis, S. praecox, Calopogon tuberosus, Calo. pallidus, Pogonia ophioglossoides, Cleistes bifaria, Cleistes divaricata, etc.) and in a less moist environment, so the typical spring orchid hunter won't be looking in the right place at the right time for it. It can be easily distinguished from
Spiranthes vernalis by the flower size (roughly half that of
S. vernalis), the later blooming time, and the fact that the stalk is leafless by the time it flowers, the rosette of wide, tear-drop shaped, highly frost-resistant leaves long withered by anthesis. Instead of a typical bundle of fleshy roots as seen with many other
Spiranthes species, this species bears a single tuber-like root, hence the specific epithet.
I happened to discover this plant growing in my parents' yard on a brief visit to the Tallahassee, Florida area.
